Deo Raj, was a zamindari (estate) situated in what is now Aurangabad district of Bihar.
These migrant Rajputs along with local Hindu Rajas played an important role in freeing the numerous Hindu shrines and temples from the Muslim rule [3] They eventually became the founders of the Deo Raj estate.
The Deo Rajas were among a number of Rajput migrant groups to arrive in Southern Bihar and they replaced the previous Umga chiefs who had fallen to Muslim invasion.

They also refused to join the nearby tribal uprisings including the Santhal rebellion.
